Taking a look at the recipients, http://developers.facebook.com/fbFund.php?tab=recipients http://developers.facebook.com/fbFund.php?tab=recipients there are definitely some which are 'infrastructure' rather than "apps": HotBerry: Frameworks and mechanics allowing users to generate own casual games on Facebook (e.g., Pinball construction set). Watch Screencast J2Play: A social gaming platform for pc, mobile, and web game developers. However, the details announced about the next iteration of the fund may preclude these sorts of entrants. The issue is that while the finalists will chosen by the fbFund committee, the winners will be chosen by Facebook's users. I think it would be hard to "sell" a non-app to them, unless you had compelling instances what the app could do.
